Two sides of a triangle are of lengths 5 cm and 1.5 cm. The length of the third side of the triangle cannot be

Given: two sides are given.

Let AB = 5cm and BC = 1.5cm


Third side AC should:


AB-BC < AC < AB + BC


5-1.5 < AC < 5 + 1.5


3.5 < AC < 6.5


Hence, it cannot be 3.4 because it is less than 3.5.


Option D is correct.
